Ischemic stroke susceptibility associated with ALPK1 single nucleotide polymorphisms by inhibiting URAT1 in uric acid hemostasis.

Objectives: Ischemic stroke (IS) prevalence rising annually, the necessity of discovering non-interventional genetic influences is progressing. Single nucleotide polymorphism (SNP) plays a pivotal role in stable inheritance of disease susceptibility. Based on the relationship between Alpha- Kinase 1 (ALPK1) and traditional IS risk factors especially hyperuricemia, our study investigated the association and function of ALPK1 SNPs with IS susceptibility.

Risk Prediction Models for Invasive Mechanical Ventilation in Patients with Autoimmune Encephalitis: A Retrospective Cohort Study.

Methods: A multivariate predictive nomogram model was developed using the risk factors identified by LASSO regression and assessed by receiver operator characteristics (ROC) curve, calibration curve, and decision curve analysis.

Results: The risk factors predictive of severe respiratory failure were male gender, impaired hepatic function, elevated intracranial pressure, and higher neuron-specific enolase. The final nomogram achieved an AUC of 0.

Ursolic Acid Ameliorated Neuronal Damage by Restoring Microglia-Activated MMP/TIMP Imbalance in vitro.

Purpose: The oxygen and glucose deprivation-reoxygenation (OGDR) model is widely used to evaluate ischemic stroke and cerebral ischemia-reperfusion (I/R) injury in vitro. Excessively activated microglia produce pro-inflammatory mediators such as matrix metalloproteinases [MMPs] and their specific inhibitors, tissue inhibitors of metalloproteinases [TIMPs], causing neuronal damage. Ursolic acid (UA) acts as a neuroprotective agent in the rat middle cerebral artery occlusion/reperfusion (MCAO/R) model keeping the MMP/TIMP balance with underlying mechanisms unclear.

Association between HMGB1 genetic variants and ischemic stroke susceptibility, onset age, and recurrence risk among Chinese Han individuals.

Objectives: Ischemic stroke has long been a global health threat. Genetic factors, a looming risk for ischemic stroke, remain unexplored. The high-mobility group box 1 (HMGB1) protein showed a connection with the occurrence and development of ischemic stroke.

Genetic polymorphisms of pri-let-7f, gene-environment and gene-gene interactions, and associations with ischemic stroke risk in Liaoning Province.

Objective: The incidence of stroke has been rising annually and investigations into traditional risk factors have led to increased attention on genetic factors. In this study, we focused on the pri-let-7f gene, and investigated the association between pri-let-7f gene polymorphisms and ischemic stroke (IS).

Methods: This case-control study included 1803 patients and 1456 healthy controls of Han ethnicity living in Liaoning Province.

Ursolic acid promotes microglial polarization toward the M2 phenotype via PPARγ regulation of MMP2 transcription.

Microglia, which are the primary inflammatory cells of the brain, can undergo phenotypic switching between M1 and M2 polarization, which have opposing effects on inflammation. Peroxisome proliferator-activated receptor gamma (PPARγ) is a member of the nuclear receptor family of ligand-inducible transcription factors, and PPARγ is known to regulate M2 macrophage polarization. Previous studies have shown that the natural pentacyclic triterpenoid ursolic acid (3β-hydroxy-urs-12-en-28-oic acid; UA) influences microglial activation.

Genetic variants in the promoters of let-7 are associated with the risk and age at onset of ischemic stroke: A case control study.

Purpose: Let-7 family members serve as crucial regulatory molecules in the pathogenesis of ischemic stroke. We predicted that genetic variations in the let-7 family's promoters may be linked to the risk of ischemic stroke. The connection of rs10877887 and rs13293512 in the let-7 family promoters with liability to ischemic stroke was explored in this study.

Genetic variation within the pri-let-7f-2 in the X chromosome predicting stroke risk in a Chinese Han population from Liaoning, China: From a case-control study to a new predictive nomogram.

Background And Objectives: Stroke is the most common cause of disability and the second cause of death worldwide. Therefore, there is a need to identify patients at risk of developing stroke. This case-control study aimed to create and verify a gender-specific genetic signature-based nomogram to facilitate the prediction of ischemic stroke (IS) risk using only easily available clinical variables.
